They are characterized by being lightweight, corrosion-resistant, and low-cost, and are widely used in packaging, construction, electronics, medical and other fields.
[0003] Plastic products are prone to burrs during processing. For example, the edges of common plastic sheets are often burrs. Since plastic sheets come in various sizes, removing burrs with a utility knife or handheld grinder is time-consuming, inefficient, and inconsistent. It is also easy to get scratched by the burrs, which affects the efficiency of burr removal. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a burr removal device for processing plastic products, which solves the problems that removing burrs by using a utility knife or hand-held grinder is time-consuming, inefficient, and inconsistent due to the variety of plastic sheet sizes, and is also easy to be scratched by the burrs, thus affecting the burr removal efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a burr removal device for processing plastic products, including a worktable, a support leg connected below the worktable, multiple rollers rotatably mounted on the worktable via bearings, an opening slot on the worktable, guide plates connected to both sides of the worktable, a drive motor fixedly mounted on one side of the worktable, and a threaded rod connected to the output shaft of the drive motor;
[0006] The threaded rod has a first mounting plate and a second mounting plate installed symmetrically at both ends. Both the first mounting plate and the second mounting plate have connecting holes. Both the first mounting plate and the second mounting plate have a connecting shaft rotatably mounted on them via bearings. A sanding belt wheel is fixedly mounted on the connecting shaft.
[0007] A sanding belt is installed on the sanding wheel, a slider is slidably connected to the guide plate, a fixed rod is connected above the slider, a sliding sleeve is slidably connected to the fixed rod, multiple connecting rods are connected to the sliding sleeve, a connecting plate is connected to the connecting rod, and a pressure plate is connected below the connecting plate.
[0008] As a further embodiment of this utility model: the threaded rod is rotatably connected to the bottom of the workbench via a bearing, and the two ends of the threaded rod are provided with threads in opposite directions. Both the mounting plate one and the mounting plate two are fixedly installed with mating sleeves, and the threaded rod is threadedly engaged with the mating sleeves.
[0009] As a further embodiment of this utility model: the guide plate is T-shaped, one end of the guide plate abuts against the worktable, the other end of the guide plate is connected to a baffle, and multiple rollers on the worktable are arranged at equal intervals.
[0010] As a further embodiment of this utility model: a spring is sleeved on the fixing rod, there are two connecting rods arranged vertically, one end of the spring is connected to the top of the fixing rod, and the other end of the spring is connected to the sliding sleeve.
[0011] As a further embodiment of this utility model: the pressure plate is L-shaped, a rubber pad is connected below the pressure plate, and anti-slip texture is provided below the rubber pad.
[0012] As a further embodiment of this utility model: a working motor is fixedly installed below the second mounting plate, a guide rod is connected to the wall of the opening slot, the output shaft of the working motor is connected to the connecting shaft on the second mounting plate, and the guide rod slides through the connecting hole and slides with the first mounting plate and the second mounting plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This burr removal device for plastic product processing comprises a drive motor, a threaded rod, a working motor, a connecting shaft, a sanding belt wheel, a sanding belt, and a guide rod. By activating the drive motor to rotate the threaded rod, mounting plates one and two move opposite each other along the threaded rod on the guide rod, thereby changing the distance between them. This facilitates the installation of sanding belts of different sizes by the operator. The working motor, through the connecting shaft, drives the sanding belt wheel to rotate, which in turn drives the sanding belt to move, thus removing burrs from the edges of the plastic sheet with high consistency. The device is also easy to adjust, improving its applicability and processing efficiency.
[0015] 2. This burr removal device for processing plastic products consists of a guide plate, a slider, a fixed rod, a spring, a sliding sleeve, a connecting plate, and a pressure plate. The operator presses down on the pressure plate, causing the sliding sleeve to slide down the fixed rod and stretch the spring. A rubber pad under the pressure plate makes contact with the plastic sheet, and the L-shaped pressure plate hooks onto one edge of the plastic sheet. Pushing the pressure plate causes the slider to slide along the guide plate, allowing the other edge of the plastic sheet to contact the sanding belt, thus removing the burrs. During the process, the connecting plate protects the worker's hands, preventing accidents. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a burr removal device for processing plastic products, including a worktable 1, a support leg 2 connected below the worktable 1, multiple rollers 3 rotatably mounted on the worktable 1 via bearings, an opening slot 4 on the worktable 1, guide plates 5 connected to both sides of the worktable 1, a drive motor 6 fixedly mounted on one side of the worktable 1, a threaded rod 7 connected to the output shaft of the drive motor 6, mounting plates 8 and 9 symmetrically mounted through both ends of the threaded rod 7, the threaded rod 7 rotatably connected below the worktable 1 via bearings, and the two ends of the threaded rod 7 are provided with threads in opposite directions, a mating sleeve 20 fixedly mounted in both mounting plates 8 and 9, the threaded rod 7 and the mating sleeve 20 threadedly engaged, the threads in opposite directions at both ends of the threaded rod 7 allow the mounting plates 8 and 9 to move in opposite directions along the threaded rod 7 via the mating sleeve 20 when the threaded rod 7 rotates, thereby adjusting the spacing to facilitate the worker to attach the sanding belt 13 to the two sanding wheels 12, and improving applicability.
[0023] Both mounting plate 8 and mounting plate 9 have connecting holes 10. Both mounting plates 8 and 9 have connecting shafts 11 rotatably mounted on them via bearings. A sanding wheel 12 is fixedly mounted on the connecting shaft 11, and a sanding belt 13 is mounted on the sanding wheel 12. A working motor 24 is fixedly mounted below mounting plate 9. A guide rod 25 is connected to the wall of the slot 4. The output shaft of the working motor 24 is connected to the connecting shaft 11 on mounting plate 9. The guide rod 25 passes through the connecting hole 10 and slides with mounting plate 8 and mounting plate 9. When the threaded rod 7 drives mounting plate 8 and mounting plate 9 to move, mounting plate 8 and mounting plate 9 will slide synchronously on the guide rod 25. Thus, the guide rod 25 guides and restricts the movement of mounting plate 8 and mounting plate 9, preventing skewing.
[0024] A slider 14 is slidably connected to the guide plate 5. The guide plate 5 is T-shaped. One end of the guide plate 5 abuts against the worktable 1, and the other end of the guide plate 5 is connected to a baffle 21. Multiple rollers 3 on the worktable 1 are arranged at equal intervals. The T-shaped design of the guide plate 5 can restrict the slider 14 and prevent the slider 14 from moving up and down. The baffle 21 can block the slider 14 and prevent the slider 14 from falling off.
[0025] A fixed rod 15 is connected above the slider 14. A spring 22 is sleeved on the fixed rod 15. There are two connecting rods 17 arranged vertically. One end of the spring 22 is connected to the top of the fixed rod 15, and the other end of the spring 22 is connected to the sliding sleeve 16. When the pressure plate 19 is pressed down, the spring 22 will be stretched. After the pressure plate 19 is released, the spring 22 will rebound and pull the sliding sleeve 16 to move the pressure plate 19 upward, which makes it easier for the staff to take out and place the plastic sheet.
[0026] A sliding sleeve 16 is slidably connected to the fixed rod 15. Multiple connecting rods 17 are connected to the sliding sleeve 16. A connecting plate 18 is connected to the connecting rod 17. A pressure plate 19 is connected below the connecting plate 18. The pressure plate 19 is L-shaped. A rubber pad 23 is connected below the pressure plate 19. The rubber pad 23 has anti-slip texture. The L-shaped pressure plate 19 can contact and abut against one edge of the plastic plate, thereby hooking the plastic plate to facilitate the worker to push it forward. The rubber pad 23 can increase friction to prevent slippage. In addition, the roller 3 can help the worker to pull back the plastic plate.
[0027] The working principle of this utility model is as follows:
[0028] During operation, the drive motor 6 is started to rotate the threaded rod 7, causing the mounting plate 8 and mounting plate 9 to move opposite each other on the guide rod 25 along the threaded rod 7 through the mating sleeve 20. This changes the distance between the mounting plate 8 and mounting plate 9, making it easier for workers to install sanding belts 13 of different sizes. The working motor 24 can drive the sanding wheel 12 to rotate through the connecting shaft 11, thereby driving the sanding belt 13 to move. Then, the pressure plate 19 is pressed down, causing the sliding sleeve 16 to slide down along the fixed rod 15 and stretch the spring 22. As the pressure plate 19 moves down, the L-shaped pressure plate 19 can hook onto one edge of the plastic plate, and the rubber pad 23 can come into contact with the plastic plate. Then, the pressure plate 19 is pushed, causing the slider 14 to slide along the guide plate 5, so that the other edge of the plastic plate can come into contact with the sanding belt 13 to complete the burr removal work. During the process, the connecting plate 18 can protect the worker's hands.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
